First, find what percentage of students had 3 or more by adding up your known percents:

45% + 23 % + 21% + x% = 100%
x = 11%

Since you're given that 96 students had 2 or more, you add up the percentages of 2 and 3 or more:

11 + 21 = 32%

Now set up a proportion that relates it to the whole:

\frac{96 students}{32 percent} = \frac{x students}{100 percent}

This will allow you to find the total number of students at the school.

Cross multiplying and solving for x results in 300 total students.

Question 1:
45% had one or more absences. 45% of 300 students is 135 students.

Question 2:
As we found before, 11% of students had three or more. 11% of 300 is 33 students.

sergeinik [125]
If you would like to solve 26/57 = 849/5x, you can do this using the following steps:

<span>26/57 = 849/5x          /*(5x)
</span>26/57 * (5x) = 849     /*57
26 * 5x = 849 * 57    /26
5x = 48393/26        /5
x = <span>48393/(26*5)
x = 372.25

The correct result would be </span><span>372.25.</span><span>

bagirrra123 [75]

Answer:

B) 1153000

Step-by-step explanation:

Given

See attachment

Required

Number of households without computer in 2009

From the attachment, we have:

n=5170000 --- survey

p = 22.3\% --- proportion without computer

So, the actual number is:

Number = p * n

Number = 22.3\% * 5170000

Number = 1152910

Number \approx 1153000

<em>Hence: (B) is correct</em>
